Laminated microfluidic structures and method for making

A method for laminating at least two polymeric components to form a laminated, polymeric microfluidic structure, comprising:

• applying a weak solvent to a surface of one of the at least two components at a first temperature;
• adjacently contacting opposing surfaces including the surface having the applied weak solvent, of the at least two components;
• and
• creating a thermal activation condition by raising the temperature to a second temperature that is greater than the first temperature for thermally activating the weak solvent, wherein the weak solvent has a chemical formula of:
• where,
• R1=H or R, where R=alkyl or is absent, and
• R2=H or R, where R=alkyl or is absent.
